Peridot, the designated birthstone for those born on August 16th, is a gemstone renowned for its vibrant green color and rich historical significance. As a variety of the mineral olivine, peridot stands out for its unique geological origins and the cultural reverence it has received across centuries. Known as the "gem of the sun" by the ancient Egyptians, peridot has been cherished for its beauty and symbolism. It is one of three official birthstones for the month of August, alongside spinel and sardonyx, but is widely regarded as the primary and most well-known of the trio. Its distinctive yellowish-green to greenish-yellow hues, caused by the presence of iron, make it a unique presence in the gemological world, as it is found in only one color family. This article explores the properties, history, cultural importance, and care of peridot, offering a comprehensive look at this remarkable gemstone.
The significance of peridot extends beyond its visual appeal. It is a gemstone formed under extreme geological conditions, found in the hardened lava that carries it from deep within the Earth’s mantle and even in meteorites that journeyed from outer space. This celestial connection, combined with its long history of human use, makes peridot a subject of fascination for gemologists, collectors, and jewelry enthusiasts alike. From ancient Egyptian talismans to modern anniversary celebrations, peridot's journey through time highlights its enduring value and allure.
History and Lore
Peridot's history is as rich and colorful as its appearance. The gemstone has been admired since ancient times, with its use dating back to around 1500 BC. The Egyptian island of Zabargad, historically known as Topazios, is the oldest recorded source of this August birthstone. Mining on the island may have begun around 340–279 BCE. Although the island produced beautiful peridot, its harsh conditions earned it ominous names like "Island of Death" and Ophiodes ("snake island"). Despite these challenges, peridot from Zabargad has been prized for centuries and remains highly desirable, with fine specimens displayed in prestigious museums worldwide.
The ancient Egyptians held peridot in particularly high regard, calling it the "gem of the sun." They believed it protected its wearer from the terrors of the night and evil spirits. This protective quality was a central part of its lore, and the gemstone was often used as a talisman. The Egyptians were not the only culture to value peridot; it has been valued in many ancient and medieval cultures. The word "peridot" itself is believed to derive from the Arabic word faridat, meaning gem.
Throughout history, peridot has often been confused with other gems, most notably topaz and emerald. The Red Sea island of Topazios, a purported source of the name "topaz," actually produced peridot. This historical confusion is evident in some of the world's most famous gem collections. The Shrine of the Three Holy Kings in Germany’s Cologne Cathedral is decorated with 200 carats of gems that were long believed to be emeralds but are, in fact, peridot. Some historians even speculate that Cleopatra’s famous emerald collection may have been comprised of peridot, further illustrating the gemstone's long-standing misidentification with other green stones.
In more modern times, peridot's popularity has solidified its place as the primary birthstone for August. While sardonyx was the original birthstone for August, peridot became popular in more modern times, and spinel was recognized more recently to offer more variety for August-born individuals. Peridot is also the gem given to celebrate a 16th wedding anniversary, marking its significance in modern celebratory traditions.
Geological Formation and Sources
Peridot possesses a unique geological story that distinguishes it from many other gemstones. It is the yellowish green to greenish yellow gem variety of the mineral olivine. What makes peridot particularly fascinating is the extreme conditions under which it forms. Unlike many gems that crystallize in the Earth's crust, peridot can be found in the hardened lava that carried it from deep within the Earth’s mantle. This deep-Earth origin is one reason for its relative rarity and unique characteristics.
Adding to its extraordinary nature, peridot is also one of the few gemstones found in meteorites that traveled from outer space. This extraterrestrial occurrence connects the gemstone to the cosmos, enhancing its mystique. The presence of peridot in meteorites provides scientific evidence of its formation in space, making it a truly universal gemstone.
Today, most of the peridot seen in jewelry comes from a variety of terrestrial sources. Key modern sources include China, Myanmar, Pakistan, Tanzania, Vietnam, and the United States. The United States, specifically, has Arizona as its main source of this August birthstone. Peridot can also be found in exotic locales like Peridot Beach, Hawaii, where the sands shimmer a luminous green due to the presence of peridot crystals.
Historical sources remain highly prized. The Egyptian island of Zabargad is still revered for the quality of its peridot, and specimens from this location are considered superior by many connoisseurs. Myanmar (formerly Burma) is another important source. On the northern slope of Kyaukpon, a mountainous region near the gem city of Mogok, loose peridot crystals can sometimes be found in crevices. The finest-quality peridot from this locality is noted for its deep color and superb transparency.
Gemological Properties
Peridot is defined by a distinct set of gemological properties that contribute to its visual appeal and durability. Its most defining characteristic is its color. Peridot is known for its distinctive yellow-green hue, which can range from pale lime green to a richer olive shade. This color is consistently green under various lighting conditions, a rare trait among gemstones, as its color is caused by the presence of iron in its chemical composition. Unlike some gems that can appear different in artificial light, peridot maintains its vibrant green appearance.
As a variety of the mineral olivine, peridot has a specific chemical formula and crystal structure. While the provided sources do not specify the exact hardness on the Mohs scale, refractive index, or detailed chemical composition beyond its status as olivine and the role of iron in its color, its properties are sufficient for its use in jewelry. Its durability allows it to be fashioned into a variety of cuts and settings, making it a versatile choice for rings, necklaces, and other adornments.
The visual appeal of peridot is enhanced by its clarity and brilliance. When cut and polished, it exhibits a lively sparkle that highlights its rich green color. Its unique single-color range makes it instantly recognizable and sets it apart in the world of colored gemstones.
Symbolism and Metaphysical Beliefs
Across cultures and eras, peridot has been imbued with deep symbolic meaning and metaphysical beliefs. In ancient Egypt, it was revered as a protective stone, believed to ward off evil spirits and the terrors of the night. This association with protection has persisted through history, making peridot a popular talisman for travelers and those seeking safety from harm.
Beyond protection, peridot is also associated with positivity and prosperity. Its vibrant green color, reminiscent of new growth and nature, lends itself to symbolism related to abundance and good fortune. Some sources suggest that peridot can bring happiness and joy to its wearer, enhancing positive emotions and outlooks.
In the context of modern metaphysical beliefs, peridot is often linked to the heart chakra, promoting emotional healing and balance. It is believed to help release negative patterns and open the heart to new experiences and relationships. For those born on August 16th, wearing peridot is thought to harness these positive energies, providing a source of strength and well-being throughout the year.
The gemstone's association with the sun in ancient times also ties it to vitality and energy. As the "gem of the sun," peridot was believed to hold the power of light, bringing warmth and life to its bearer. This celestial connection continues to be a point of fascination, linking the wearer to the powerful forces of nature and the cosmos.
Care and Cleaning
To maintain the beauty and integrity of peridot jewelry, proper care and cleaning are essential. While peridot is durable enough for everyday wear, it requires some attention to prevent damage. The sources do not provide specific hardness ratings or cleavage information, but as with all gemstones, it is advisable to handle it with care.
Cleaning peridot can be done using warm, soapy water and a soft brush. It is important to avoid harsh chemicals, ultrasonic cleaners, and steam cleaning, as these could potentially damage the stone or its settings. After cleaning, the jewelry should be rinsed thoroughly and dried with a soft, lint-free cloth to restore its shine.
When not being worn, peridot jewelry should be stored separately from other pieces to avoid scratches. A soft pouch or a lined jewelry box is ideal for storage. If any damage is noticed, such as loose settings or chips, it is best to consult a professional jeweler for repairs to ensure the gemstone remains secure and preserved for future generations.
